(orzo-ssi' Thisinvention relates to metal weather strips for the tongue, and is toowide to indent the sash and sash guides for windows and especially to toform its own groove when the sash swells an abstrips and sash guides ofthis type which may be normal amount. The present invention avoids usedin windows in which the sashes slide within these disadvantages byproviding a ridge or bead.

The modification shown in Figure 4 'isv generalhr similar to the oneshown in Figure 1, diilering from it only in the construction of theparting -strip 20 and the ilanged edges of the weather strips 2I and 22.In this form of the invention thel parting strip 20 is made of sheetmetal, as in the rst form, but is provided with a illling made o! wood,impregnated paper, or other suitable material. The ilanged edge of theweatherstrip'2I is bent out and back toY form a tongue 2Id oir doublethickness lying against the edge of the trim stop I5 and the extremeedge 2 Ic lies in the same plane as the body o! th strip ZI and nts inunder With this construction the metal 2id lying against thetrim stop I5is of double thickness, which makes it stronger and allows roomior theaccumulation of 'more' coats of paint on the exposed portion Ila of thestop .I5 facing the sash I0.

Both of the constructions shown, as well as other modications not shown,are simple and economical to produce. Each of the two pieces ofweatherstrip is the same as the other one turned end for end, so bothcan be produced in a single set of rolls. The metal parting strip, beingof box-section, is quite rigid and can be se. curely held by few screws.seen that the entire assembly is economical to produce and apply,besides providing all-metal guiding surfaces for the window sashes.

What I claim is:

l. In combination, a window frame member, a pair of wooden stops securedthereto in spaced relation, a parting stop secured to the face of saidframe member between said wooden stops and dividing the space betweenthem into two channels, said parting stop having metallic side stripltohinder the lnv From this, itcan be surfaces, weather strips in each ofsaid channels having their edges held by said stops, said weather stripsbeing separate from said parting stop and having 'flanges lying againstthe sides of said wooden `stops and shoulders fitting against the sidesof the parting strip.

2. In combination, a window frame member having a flat face, a stopsecured against one edge o! said frame member and projecting beyond theface thereof, `a weather strip lying on the face of said frame memberwith a portion fitting into a slot in said stop, said weather striphaving a ange lyingjagainst the side of said stop and a shoulder spacedand facing away from said lstop, a parting stop lying against saidshoulder and securedto the faceof1 said frame member, a

Asecondweather strip having a shoulder tting against the opposite side-of said parting stop from said first shoulder, said second weatherstrip alsohaving an upstanding flange spaced from ysaid shoulder and aportion projecting beyond said ilange, and a third stop secured to saidframe member and fitting over said projecting portion and against saidflange.

3. In combination, a window frame member having fia't sides, a pair ofstops each secured directly o n a iiat side o! said frame member andforming therewith a channel for the edge of a window sash, one of saidstops having a metallic surface and the other a wooden lateral surfacefacing said metallic surface, and a metal weather strip lying in saidchannel, said weather strip having portions extending outwardly of saidchannel and covered by said stops and having-a flange covering a part ofsaid wooden lateral surface.

4. A sash guide comprising parallel strips Aof metal each having aflattened inner edge, a reversely bent portion adapted to extend ingrooves formed in afwindow sash and a channel wall comprising areversely bent outer edge residing outwardly of said sash, and a sashparting stop comprising a separate hollow metal strip jointly overlyingsaid inner edges; and means passing between said edges for securing saidparting stop vdirectly to a window frame thereby snaring said inneredges between said stop and a window frame.
